Why Using a Strength in a New Way Lifts Your Mood

Most strengths advice stops at the quiz. The research lift comes from a different move: pick one strength you already have and use it in a new way.

Most "play to your strengths" advice stops at the easy half: take the quiz, learn your top five, screenshot the list. Nothing in your week changes. The research lift comes from a different move entirely. The exercise with the most durable evidence is not naming your strengths, it is picking one you already have and using it in a new way today. In the foundational positive psychology trial, that single instruction was one of only two exercises whose happiness and lower depression scores still showed up six months later.

The identifying part is the easy step. The using part is where the lift quietly lives, and most articles skip it.

What Is a Signature Strength?

The VIA framework, developed by Christopher Peterson and Martin Seligman in their 2004 Character Strengths and Virtues handbook, sorts twenty-four character strengths under six broader virtues like wisdom, courage, humanity, and transcendence. Curiosity, kindness, perspective, gratitude, humor, hope, bravery, and zest are a few. A "signature" strength is not just one you rate high on. It is one that meets a tighter bar: it feels like the most authentic you when you use it, you reach for it often without being told, using it energizes you rather than draining you, and the people who know you well would name it back to you if asked.

Most adults can identify three to seven of these. They are less a label than a description of who you already are at your best.

What the Research Actually Shows

In the 2005 landmark trial published in American Psychologist, Martin E. P. Seligman, Tracy A. Steen, Nansook Park, and Christopher Peterson tested five positive psychology exercises against a placebo "early memories" writing task. The exercises ran for a single week, by email, with no therapist contact. Participants were followed for six months.

Two exercises produced gains in happiness and reductions in depressive symptoms that were still present at the six-month follow-up: "three good things" (writing down three things that went well each day, with a brief explanation) and "use your signature strengths in a new way" (identify one of your top strengths, then deliberately use it in a way you have not used it before, every day for a week). Brief, written, done at home.

A 2026 meta-analysis published in Clinical Psychology Review by Ausiàs Cebolla and colleagues pooled 114 randomized trials and 20,853 participants to ask a sharper question: which character strengths can interventions actually grow, and does growing them mediate the wellbeing gains? Across the five strengths with enough trials to meta-analyze, interventions reliably raised perspective, kindness, and gratitude, and the wellbeing gains ran through that growth. Humor and hope interventions still raised wellbeing, but not by raising humor or hope themselves, suggesting they help through other routes. Honest takeaway: cultivating a strength is most reliable when the strength is something like kindness, perspective, or gratitude, and even where it works the effects are modest.

(One careful note on terminology: this is hope as a VIA character strength, the disposition. The trainable cognitive skill of hope as agency plus pathways, built on a separate research program by C. R. Snyder, is a different construct that happens to share the English word.)

Why "Use It in a New Way" Works (and What Else Might)

The most interesting finding may be the honest twist. When Myriam Mongrain and Tracy Anselmo-Matthews ran a close replication of Seligman's trial in 2012 in the Journal of Clinical Psychology, the strengths-in-a-new-way exercise and three good things both produced the lasting gains again. So did the "positive early memories" placebo group. All three improved happiness and reduced depressive symptoms a meaningful amount, and the supposed-placebo more or less matched the active exercises.

The authors proposed that the common mechanism might not be strengths specifically. It might be the simple daily act of engaging with positive, self-relevant content for a few minutes, on a steady cadence.

Read constructively, that is a feature. It means the active ingredient is not exotic. A small, intentional, daily dose of something positive and personally meaningful seems to do real work, and the strengths exercise is one nicely structured version of it. The same logic is why a small future-facing exercise like writing your best possible self keeps showing up in this literature, and why reading one positive line a day is more than a soft habit.

Five Concrete Ways to Use a Strength in a New Way Today

The "new way" part is the active ingredient, so vary it. Pick one strength you already have, and try a single small move you have not made with it before:

Curiosity. Walk a slightly different route home and notice three specific things you have never seen on that block.
Kindness. Text one specific thank-you to someone who helped you in the last month, naming the thing they did.
Perspective. Ask a friend whose judgment you trust how they would think about a small decision you are turning over.
Gratitude. Out loud, over dinner or to yourself, name three particular details from today, not "I'm grateful for my health" but "the cold side of the pillow at 11pm."
Humor. Tell one small story tonight that you have not told before, the kind that lands a smile.

The point is not the specific move. It is that you used a strength of yours in a way you would not have, on purpose.

A Few Minutes a Day, with Positive

The Positive app is a small daily dose of exactly the kind of positive, self-relevant content the research keeps pointing back to. One handpicked quote a day, opened on a fixed cue, is a thirty-second version of the same mechanism the strengths exercise rides. And browse-by-topic lets you pull a line on courage, kindness, curiosity, or gratitude when you want today's strength move to start somewhere specific. No accounts, no ads if you go Premium, and it is free to download.

You already have these strengths. The lift is in using one of them today in a way you have not used it before.
